WATER-JOINT FOR ROTARY PUDDLING-FURNACES.

SPECIFICATION forming part of Letters Patent No. 295,867, dated March 2 5, 1884. Application filed June 22, 1883. (N model.)

To aZZ whom it may concern..-

Be it known that we, JOHN GRIFFEN and J EssE HALL, J r;, citizens of the United States,

and residents of Phcenixville, Chester county,

5 Pennsylvania, haveinvented certain Improvements in ater-Joints for Rotary Puddling- Furnaces, of which the following is a specification.

Our invention relates to certain improvements in what areknown as the water-joints of rotary puddlersthat is, the joints which permit the free introduction of water to the water-jacket of the puddler while the latter is rotating-our improvements, which are fully I 5 described hereinafter, having been especially directed to the securing of a joint which will not leak, and to the maintenance of a constant supply of water in the jacket of the puddler. In the accompanyingdrawings, Figure 1,

Sheet 1, is a side view of a rotary puddler,

showing our improved water-joint; Fig. 2,

Sheet '2, a transverse section partly on the line 1 2 and partly on the line 3 4., Fig. 1; Fig. 3,

Sheet 3, an enlarged sectional view of the water-joint and Figs. 4, 5, and 6, Sheet 4., perspect-ive views, illustrating the detailed construction of the several parts composing the joint.

The rotary puddler Ahas two rings, a, (one near each end,) for hearing on four flanged wheels, B-two wheels for each ring-one pair of wheels being secured to a shaft, D, and the other pair to a shaft, D, the bearings b of which are secured to beams E E, the latter forming parts of a permanent foundation orparts of a truck on which the puddler can be moved to and fro, as described in a separate application for a patent. A toothed rim, F, also surrounds the puddler, and into this gears a pinion, F,

on a driving-shaft, G.

As regards the detailed construction of the puddler, it will suffice for this application to remark that it consists of an outer casing, H, and, an inner casing, I, lined with refractory material, and that thereis a water-space, K, between the two casings, all as shown in the enlarged view, Fig. 3. A substantial band, M, surrounds and is riveted to the outer casing, H, midway, or thereabout, between the opposite ends of the puddler, and to this band is snugly fitted a ring, N, also extending round the puddler, and secured to the said band by set-screws d, Fig. 3. This ring N, composed of the annular rib m and flanges n n, forms a v permanent part of the puddler, and will be best 5 5 understood by reference to the perspective View, Fig. 6, where it will be observed that at intervals holes f exten d through the ring, these holes being continued through the band M and outer casing, H, of the puddler. Another ring, W, which is fixed, is adapted to the ring N, as shown in Fig. 3, and this ring is internally recessed, fora purpose rendered apparent hereinafter. The ring W is composed of two semi-annular parts, bolted together at 00 00, Fig. 6 5 2, and each part is composed of two segments bolted together. The peculiar construction of these segments will be best understood byreference to the perspective view, Fig. 4, where 7 it will beobserved that each segment has a vertical flange, h, a horizontal flange, i, and an annular rib, j, situated at a distance from the flange a, but connected to the same and to the flange h by a number of webs, 70. When these twosegments are bolted together, they form 7 one-half of the ring W, the other half being composed of similar segments, excepting that they have projections p p, which embrace the two shafts D D, this being the plan adopted in the present instance of making the ring W stationary. p j

. Referring to Fig. 3, it will be seen that when the ring W is fitted over the annular rib m of the ring N there will be an annular chamber, g, which is in continuous communication with the water-space K between the two casings of the puddler through the holes f, above referred to. I

On each side of the ring W, and between the flange z and rib j, there is an annular space, 8, o

Fig. 4, in which is placed packing composed, preferably, of aseries of rings, t, Fig. 3, of leather, backed by a mass of hemp, it, against which bear the ribs of the packing-segments T, the latter being secured to the rin- WV by stud-bolts w, on tightening the nuts of which the packing will be forced against the opposite sides of the annular flange m of the ring. thereby securing a perfectly tight joint, which permits the said rib m of the ring N to rotate with the puddler, and within the ring WV, withoutdanger of any leakage of water introduced into the annular chamber q.

Owing to the presence of the webs k, each follower is necessarily made in comparatively short segments; but these segments are so near to each other that each follower composed of a number of segments has practically the same effect on the packing as a follower made of one continuous ring. Vater is introduced under pressure into the chamber 1 through a pipe,

' y, at the lowest point of the ring W, and passes through the said chamber and through the hol es f into the water-space K between the two casings of the puddler, the water escaping through a pipe, y, at the highest point of the ring WV-an arrangement by which the main tenance of the water-space K and the annular chamber (1 constantly full of water is assured,

thereby enabling the inner casing of th'epud-. 2o dler to withstand the heat to which it is subjccted.

Ve claim as our invention The combination of a rotary puddler and its ring m with the ring W, composed of two 25 semi-annular parts, each composed of two segments, and each segment having a flange, z, and rib j, situated apart from each other, but connected together by webs 70, all substantially as specified.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
